dc.description.abstract | Basmati rice (
Oryza sativa
L.) is preferred by many Kenyans yet its yield per hectare is low. This challenge led to
initiation of Basmati hybrid rice project in Kenya with a goal of leaping yield benefits of het
erosis. Since quality
traits in Basmati are under recessive gene control, then the two parents in hybrid programme must possess the
traits to avoid their masking at F
1
by any other dominant gene. In the process of breeding for suitable parents,

33S (V3) were crossed to produce F
1
. All the F
1
s plants had strong presence of anthocyanin
on the base of their stems but segregated at F
2
population. Thus, the objective of this study work was to evaluate
and understand the mode of anthocyanin gene segregation at F
2
population as a potential morphological marker.
The F
2
population was analyzed to test hypothesis that
anthocyanin
marker(s) i
s under simple Mendelian gene
control. However, the results obtained indicated that F
2
did not obey the Mendelian laws of gene segregation.
This led to the conclusion that anthocyanin marker experience segregation distortion in F
2
population | |
